APPARATUS FOR MAKING TOILET-TABLETS.

SPECIFICATION forming part of Letters Patent No. 718,713, dated January 20, 1903.

Application filed August 29, 1902. Serial No. 121,428. (No model.)

T at whom it may concern:

Be it known that LVViLLiAM KROPFF, a citizen of the United States, and a resident of New York city, county and State of New York,have invented certain new and useful Improvements in Apparatus for Making Toilet-Tablets, of which the following is a specification.

This invention relates to an improved apparatus for making perfumed toilet-tablets such as are worn by ladies to perfume their clothing.

The invention relates to improved means for so securing the stem or handle to the tablet that it will be properly centered and will become firmly embedded therein without ad ditional fastening devices.

In the accompanying drawings, Figure l is a plan of my improved apparatus with the upper die omitted; Fig. 2, a side view of the apparatus; Fig. 3, a side view of the lower die and the mold, showing them disconnected;

Fig. 4:, a side view of the upper die; Fig. 5,"

a section on line 5 5, Fig. 4; Fig. 6, a section on line 6 6, Fig. 3, showing the wire in position; Fig. 7, a perspective View of the tablet made by the apparatus, and Fig. 8 an end view thereof.

The apparatus is composed, essentially, of three partsviz., an upper die, a lower die, and an annular mold adapted to embrace the dies and made detachable therefrom.

The letter A represents the bed-plate, from which projects the lower die a, corresponding in shape to the configuration which is to be given to the tablet B. The drawings show such tablet to be heart-shaped; but such shape may obviously be varied. At one side of the die ct there projects, furthermore, above bedplate A a key or feather a, which extends to a point slightly above die Ct, Fig. 6, and serves as a support for the wire or stem f. The annular mold D is made of a contour to embrace die a and is adapted to be removably locked to the bed-plate. The locking mechanism is shown to consist of eccentric disks a rotatable by means of handles a upon stubs a of plate A and adapted to engage segmental notches d of mold D. In order to accommodate the key a, the lower section of mold D is provided with an upright slot d. This slot is slightly longer than the height of the key a, so that when the mold D is placed over the lower die a perforation is formed between the upper end of the key and the upper edge of the slot. This perforation extends transversely through the entire thickness of the I mold and is of a diameter to snugly fit the stem, which is to be molded into the tablet. In this way the length of the stem does not depend upon the thickness of the mold, and, further, the stem is rigidly held in a horizon-' tal position, so that its inner end, which projects through the perforations over the die, will not sag, Fig. 6.

The upper die 6, depending from a suitable plunger E, is adapted to enter the upper section of mold D and is of a contour corresponding to that of the mold and the lower die.

In use atwisted wire or other suitable stem f, which is to constitute the handle of the tablet, is placed upon key a', so that its inner end projects above die a, Fig. 6. The mold is then slipped over the lower die a and locked to bed-plate A by means of the eccentrics a The perfumed plastic mass which is to form the tablet is now filled into the mold upon the lower die, so as to cover the free inner end of wire f. Next the'upper die is forced into the mold by means of a suitable press, so as toshape the plastic mass into the form desired. The tablet being thus properly molded the upper die is raised and the mold is unlocked from the bed-plate and lifted oif the lower die, so that the tablet may be removed.

It will be seen that in the finished tablet the wire f is properly centered and securely embedded within the body of the plastic material, which has been tightly compressed around the same, so that a simple, neat, and reliable connection is formed. The key 0, serves not only as a rest for the wire, but it also constitutes a guide by means of which the wire is always properly centered.

What I claim is-- In an apparatus for making toilet-tablets, the combination of a lower die with a key projecting above the same, annpper die, a mold adapted to surround the dies and having a slot which is of greater height than the key so as to form an intervening transverse perforation, and means for clamping the mold to the lower die, substantially as specified.

Signed by me at New York city, New York, this 28th day of August, 1902.

WILLIAM KROPFF.
